Question

Define the terms Murchana and Jaati.

Hint:

Keep the two meanings of Jaati separate: Raga Jaati determines melodic weight (5, 6, or 7 notes), while Tala Jaati determines the rhythmic frame (3, 4, 5, 7, or 9 beats).

Answer 1

Step 1: Concept
These are fundamental technical terminologies used to define the scales, structural identities, and rhythmic classifications of music.

Step 2: Defining Murchana
- Murchana refers to the linear ascending and descending structure of a raga, commonly known as Aarohana and Avarohana.
- Historically, in ancient Indian musicology, Murchana referred to the process of modal shifting of the tonic note (Graha Bhedam) to generate new scales from a parent mela. In modern practice, it simply denotes the skeletal melodic framework of a raga.

Step 3: Defining Jaati
The term Jaati has two distinct applications in Carnatic music: 1. In Ragas (Melodic): It denotes the classification of a raga based on the number of notes present in its scale: - Sampurna (7 notes) - Shadava (6 notes) - Audava (5 notes) - For example, an Audava-Sampurna raga has 5 notes in ascent and 7 notes in descent.
2. In Talas (Rhythmic): It specifies the number of beats in the Laghu component of the tala cycle. There are five rhythmic jaatis: Trisra (3 beats), Chatusra (4 beats), Khanda (5 beats), Misra (7 beats), and Sankeerna (9 beats). Final Answer: Murchana refers to the ascending and descending structural scale of a raga. Jaati refers to either the number of notes in a raga's scale or the beat-count of the Laghu in a tala.
